Fee petition mechanics · Updated June 2026
Probate litigation attorney fee petition mechanics: California Probate Court CMS as primary non-PACER Welch anchor, Cal. Prob. Code § 10800 statutory percentage ordinary fee vs. § 10830 extraordinary services lodestar bifurcation advisory, and § 10830 extraordinary fee petition and § 11420 mandatory costs to prevailing party advisory
Probate litigation solos billing hourly on California probate estate and trust administration, contested will proceedings (Cal. Prob. Code § 8250 et seq.), Cal. Prob. Code § 850 petition practice, and extraordinary services under § 10830 — whose fee documentation must cover advisory calls triggered by the California Probate Court electronic case management system petition filing date (the primary non-PACER Welch anchor in the California Superior Court Probate Division CMS — a California state court system entirely outside PACER, CM/ECF, and any federal court docketing system, with the probate petition filing date establishing the opening of the estate administration period and the Welch temporal anchor for all extraordinary fee hours from petition filing through final account), the ordinary vs. extraordinary fee bifurcation calendar, and the post-petition § 10830 extraordinary fee petition and § 11420 mandatory costs calendar — generate three billing gaps. Probate litigation is the only practice area in the fee-petition-mechanics series with DUAL fee documentation standards running simultaneously: § 10800 statutory percentage ordinary fees (4%/3%/2%/1%/0.5% of estate value, NO contemporaneous records required) and § 10830 extraordinary services lodestar (Hensley/Welch contemporaneous records required from probate petition filing date), with the billing gap arising when attorneys perform extraordinary services (will contests, § 850 petitions, trust challenges, accounting disputes) but treat all time as ordinary fee-subsumed without filing a separate § 10830 extraordinary fee petition: estate opening and § 10800/§ 10830 ordinary/extraordinary bifurcation advisory calls arriving when the probate petition filing date establishes the § 10830 lodestar anchor (7 clients × 2 calls × 42 min × 55% untracked ≈ 5.39 hrs = $1,617–$2,695/year at $300–$500/hr), contested probate hearing and § 10830 extraordinary fee documentation advisory calls arriving when will contests, § 850 petitions, and inventory disputes generate extraordinary service hours (6 clients × 3 calls × 44 min × 55% untracked ≈ 7.26 hrs = $2,178–$3,630/year), and § 10830 extraordinary fee petition and § 11420 mandatory costs advisory calls arriving when the contested proceeding reaches final account or judgment (5 clients × 2 calls × 44 min × 55% untracked ≈ 4.03 hrs = $1,210–$2,017/year). For a solo probate litigation practice, the annual billing gap is $5,005–$8,342.
TL;DR
ClaimHour captures every estate opening and § 10800/§ 10830 ordinary/extraordinary fee bifurcation advisory call that arrives when the probate petition filing date establishes the § 10830 lodestar anchor and ordinary vs. extraordinary scope must be defined from day one, every contested probate hearing and § 10830 extraordinary fee documentation advisory call that arrives when will contests, § 850 petitions to return property, and inventory and appraisal disputes generate extraordinary service hours that must be contemporaneously documented, and every § 10830 extraordinary fee petition and § 11420 mandatory costs to prevailing party advisory call that arrives when the contested proceeding reaches final account or judgment — passively, no timer, no audio, no call contents. $29–$59/mo. No PMS required.
Estate opening and § 10800/§ 10830 ordinary/extraordinary fee bifurcation advisory: calls on the California Probate Court CMS non-PACER calendar
The California Probate Court electronic case management system petition filing date — recorded in the California Superior Court Probate Division CMS (Odyssey Case Manager, eCourt, or equivalent state court case management system) — is the primary Welch temporal anchor for probate litigation billing documentation. The probate petition filing date establishes the opening of the estate administration period and the Welch temporal anchor for all attorney fees incurred from petition filing through final account, final fee petition, and judgment — in a California state court system entirely outside PACER, CM/ECF, and any federal court docketing system. Probate litigation is the only practice area in the fee-petition-mechanics series with dual fee documentation standards running simultaneously for the same case: § 10800 statutory percentage ordinary fees (4% of first $100,000, 3% of next $100,000, 2% of next $800,000, 1% of next $9,000,000, 0.5% of next $15,000,000 of estate value — no contemporaneous records required) and § 10830 extraordinary services lodestar (requiring Hensley v. Eckerhart 461 U.S. 424 (1983) and Welch v. Metropolitan Life Ins. Co. 480 F.3d 942 (9th Cir. 2007) contemporaneous records from the probate petition filing date). The billing gap occurs when attorneys perform extraordinary services but treat all time as ordinary fee-subsumed without filing a separate § 10830 extraordinary fee petition.
Two estate opening and fee bifurcation advisory call types: (1) Probate Court CMS estate opening and § 10800 ordinary fee percentage scope advisory — arrives when attorney accepts estate administration engagement and must determine ordinary vs. extraordinary fee scope from petition filing date (requiring § 10800 attorney compensation schedule: 4% of first $100,000, 3% of next $100,000, 2% of next $800,000, 1% of next $9,000,000, 0.5% of next $15,000,000; § 10810 estate value definition — property subject to administration; § 10811 personal representative compensation at same rates; § 10800 ordinary fee = filing petition, publishing notice, filing inventory, paying debts, filing accounts, distributing assets; § 10810 exclusions from estate value; probate petition filing date in California court CMS as Welch temporal anchor for extraordinary fee computation from day one — 42–50 min); (2) § 10830 extraordinary services scope and Welch contemporaneous records framework advisory — arrives when estate presents complications requiring extraordinary services (requiring § 10830 extraordinary services — "the court shall allow such additional amount as the court may consider just and reasonable for extraordinary services": will contest proceedings, contested accounts, proceedings to determine distribution, will interpretation proceedings, tax proceedings, § 850 petitions to return property, successful defense of creditor claims; distinction between ordinary fee-subsumed services (§ 10800 percentage covers) and extraordinary services requiring separate § 10830 petition; Welch contemporaneous records requirement applies to § 10830 extraordinary lodestar from probate petition filing date; § 10831 extraordinary fee petition requirements — nature of extraordinary services rendered, time spent, and hourly rate — 42–50 min). At 55% untracked: 7 clients × 2 calls × 42 min × 55% = 323.4 min / 60 = 5.39 hours = $1,617–$2,695/year at $300–$500/hr.
Contested probate hearing and § 10830 extraordinary fee documentation advisory: calls on the probate litigation calendar
Contested probate proceedings generate advisory calls throughout the probate litigation calendar because each contested matter — will contest (§ 8250 et seq.), § 850 petition to return property (§ 859 double damages for bad faith wrongful taking), inventory and appraisal dispute (§ 8800 et seq.), or creditor claim contest — generates extraordinary service hours that must be separately documented from the ordinary fee percentage baseline under § 10831 (nature of services, time spent, hourly rate, result achieved, difficulty). The § 10830 extraordinary fee petition is filed at final account alongside the ordinary § 10800 fee request — but extraordinary service hours must be documented contemporaneously from the probate petition filing date as the Welch anchor, not reconstructed at final account. Cal. Prob. Code § 859 double damages (twice the value of property wrongfully taken) for bad faith § 850 violations creates additional advisory calls whenever a third-party wrongful taking involves the "in bad faith" element that doubles the damages exposure.
Three contested probate and § 10830 advisory call types: (1) Will contest and § 10830 contested proceeding extraordinary fee documentation advisory — arrives when a will contest or objection to probate is filed (requiring Cal. Prob. Code § 8250 will contest grounds — lack of testamentary capacity (§ 6100.5 mental capacity standard), undue influence, fraud, duress, mistake, forgery, or revocation; § 8270 will contest procedure — filed before admission to probate (§ 8270(a)) or after admission (§ 8271 — within 120 days of order admitting will); § 8007 interest of person in estate — standing; will contest litigation is the paradigm § 10830 extraordinary service requiring contemporaneous records from probate CMS petition date; In re Estate of MacDonald 51 Cal.3d 262 (1990) will contest attorney fees from estate when contest was necessary; § 10830 extraordinary fee petition for will contest work must show: (a) nature of services, (b) necessity, (c) time spent from probate petition date through contest resolution, (d) reasonable hourly rate — 44–52 min); (2) § 850 petition to return property and § 10830 extraordinary fee documentation advisory — arrives when estate assets are disputed as having been wrongfully taken by a third party before or after death (requiring § 850(a)(2)(B) petition by personal representative to require third party to return property belonging to estate; § 859 double damages — "a person who in bad faith wrongfully takes, conceals, or disposes of property belonging to ... the estate of a decedent ... shall be liable for twice the value of the property recovered by an action under this part"; § 856 action may be filed in pending probate or as independent civil action; § 850 petition date as secondary non-PACER anchor (probate court CMS) for § 10830 extraordinary service hours from petition date; Conservatorship of Levitt 2008 WL 4831634 extraordinary fees for § 850 petition work — 44–52 min); (3) Inventory, appraisal, and § 8905 probate referee advisory — arrives when inventory must be filed and estate value established for § 10800 ordinary fee calculation (requiring § 8800 duty to file inventory and appraisal within 4 months of appointment; § 8900 probate referee appointed by court to appraise estate assets; § 8901 probate referee appointed by State Controller; § 8905 personal representative petition to be appointed as probate referee for independently appraised property; § 8960 final inventory and appraisal completion deadline; inventory filing date in California probate CMS as secondary non-PACER anchor; § 10800 fee calculation basis: estate value from inventory drives ordinary fee amount — errors in inventory affect both ordinary fee calculation AND extraordinary fee petition baseline; § 10810 debts and encumbrances subtracted from estate value for § 10800 ordinary fee calculation — 44–52 min). At 55% untracked: 6 clients × 3 calls × 44 min × 55% = 435.6 min / 60 = 7.26 hours = $2,178–$3,630/year at $300–$500/hr.
§ 10830 extraordinary fee petition and § 11420 mandatory costs advisory: calls on the final account and post-judgment calendar
Cal. Prob. Code § 10830 provides that "the court shall allow such additional amount as the court may consider just and reasonable for extraordinary services" — "shall allow" is mandatory once extraordinary services are proven (necessary + reasonable + documented). Estate of Pac. Valley Bank 229 Cal.App.3d 1386 (1991) establishes that the § 10830 extraordinary fee petition may be filed at any time before final distribution — but Welch contemporaneous records must trace every extraordinary service hour from the probate petition filing date as the anchor. Ketchum v. Moses 24 Cal.4th 1122 (2001) positive multiplier available for § 10830 extraordinary services in probate court when skill, novelty, or difficulty justifies enhancement. Cal. Prob. Code § 11420 costs in proceedings incorporates Cal. Code Civ. Proc. § 1032(b): prevailing party "is entitled as a matter of right to recover costs" — a mandatory cost award in contested probate proceedings, filed concurrently with the § 10830 extraordinary fee petition at final account.
Two § 10830 and § 11420 advisory call types: (1) § 10830 extraordinary fee petition and Hensley lodestar advisory — arrives when extraordinary services are complete and § 10830 fee petition must be filed with the probate court (requiring § 10830 "shall allow" mandatory standard once extraordinary services proven; § 10831 extraordinary fee petition: (a) list of extraordinary services, (b) time spent on each, (c) hourly rate, (d) result achieved, (e) difficulty of task; Hensley v. Eckerhart 461 U.S. 424 (1983) lodestar from probate petition filing date through final account; Estate of Gilmaker 57 Cal.2d 627 (1962) extraordinary services scope; Estate of Pac. Valley Bank 229 Cal.App.3d 1386 (1991) extraordinary fee petition timing — may be filed at any time before final distribution; Ketchum v. Moses positive multiplier available for § 10830 extraordinary services when skill, novelty, or difficulty justifies enhancement; PLCM Group, Inc. v. Drexler 22 Cal.4th 1084 (2000) California prevailing market rate — 44–52 min); (2) § 11420 mandatory costs to prevailing party and contested probate cost award advisory — arrives when contested probate litigation reaches judgment or order and § 11420 costs memorandum must be filed concurrently with § 10830 extraordinary fee petition (requiring § 11420 costs in proceedings — "the court shall award costs as provided in Title 14 (commencing with Section 1032) of Part 2 of the Code of Civil Procedure"; Cal. Code Civ. Proc. § 1032(b) prevailing party "is entitled as a matter of right to recover costs" — mandatory cost award; § 1033.5(a)(10) expert witness fees as recoverable costs when ordered by court; § 11003 court may allow costs of proceedings from estate when necessary; Estate of Clark 136 Cal.App.3d 673 (1982) costs in contested probate; § 11604 memorandum of costs — probate court adopts CCP § 1033 cost memorandum procedure for contested probate; concurrent § 10830 extraordinary fee petition filed with § 11420 costs memorandum; Missouri v. Jenkins 491 U.S. 274 (1989) fees-on-fees for § 10830 extraordinary fee petition preparation hours — 44–52 min). At 55% untracked: 5 clients × 2 calls × 44 min × 55% = 242 min / 60 = 4.03 hours = $1,210–$2,017/year at $300–$500/hr.
How ClaimHour fits probate litigation practice
If you handle California probate estate and trust administration, contested will proceedings (§ 8250 et seq.), Cal. Prob. Code § 850 petition practice, and § 10830 extraordinary services — with estate opening and § 10800/§ 10830 ordinary/extraordinary bifurcation advisory calls arriving when the probate petition filing date establishes the § 10830 lodestar anchor, contested probate hearing and § 10830 extraordinary fee documentation advisory calls arriving when will contests, § 850 petitions, and inventory disputes generate extraordinary service hours that must be contemporaneously documented, and § 10830 extraordinary fee petition and § 11420 mandatory costs advisory calls arriving when the contested proceeding reaches final account or judgment — and if your § 10830 extraordinary fee documentation must satisfy Hensley lodestar specificity from the probate petition filing date, the inventory and appraisal filing date, and the § 10830 extraordinary fee award date across three billing calendars (one California Probate Court CMS non-PACER non-federal, one contested proceeding litigation, one final account/post-judgment), ClaimHour was built for that gap.

How does the probate petition filing date / inventory and appraisal filing date / § 10830 extraordinary fee award date Welch three-anchor framework apply to probate litigation billing documentation?
Three Welch temporal anchors: (1) California Probate Court CMS petition filing date (California Superior Court Probate Division CMS — Odyssey Case Manager, eCourt, or equivalent state court CMS — entirely outside PACER, CM/ECF, and all federal court docketing systems) — primary anchor; establishes opening of estate administration period and § 10830 lodestar anchor; probate litigation is the only practice area in the series with primary Welch anchor in a California state COURT system (probate court CMS) rather than a regulatory database, administrative agency, law enforcement database, or government administrative records system; (2) Inventory and appraisal filing date (also in California probate court CMS) — secondary anchor; § 8800 4-month deadline; establishes estate value for § 10800 ordinary fee calculation; § 850 petition date also creates a secondary non-PACER anchor in the same probate court CMS; probate litigation is one of the few practice areas in the series where both primary and secondary Welch anchors are in the same state court CMS system; (3) § 10830 extraordinary fee award order date (probate court judgment at final account) — closing anchor; § 10830 "shall allow" mandatory once extraordinary services proven; Ketchum multiplier available for § 10830 California extraordinary services component; § 11420 mandatory costs to prevailing party incorporated Cal.
