Probate work is a professional service, but its “product” is not a physical item. It is a reliable stream of information and documents: instructions, verified estate details, legal analysis, signed forms, court submissions, the grant, and the records needed to collect and distribute assets.
Value stream mapping (VSM) makes that stream visible from the client’s perspective. It shows the work, handoffs and waiting between instruction and completion, helping a firm distinguish necessary legal judgment from avoidable delay, duplication and rework.
The aim is not to rush complex legal work or treat every estate as identical. It is to create a dependable route for standard matters, make exceptions visible, and protect time for professional judgment. Probate requirements vary by jurisdiction, so validate every form, deadline, tax rule and court control locally. For example, GOV.UK’s probate guidance sets out steps specific to England and Wales.
1. Select a clear product family and boundary
Start with a product family: standard, non-contested estate administration matters. Separate complex, disputed, cross-border or unusual estates into appropriate categories rather than blending them into a single average.
For this worked example, the boundary runs from client instruction and engagement to grant, asset collection, distribution and file closure. The scope reflects the client’s wider need, not merely obtaining the grant, and makes post-grant waiting and beneficiary communication visible. A firm could first map instruction to grant, then map distribution as a second, more detailed stream.
Map the actual process with the people doing the work: client or executor, legal assistant, fee earner, tax specialist, supervising lawyer, court and external institutions. Record touch time (active work) separately from wait time (elapsed time between steps). Include the information flow as well as the documents and tasks.
2. Current state: where time accumulates
The following fictional baseline represents 20 standard matters. It is an example for demonstrating the method, not an industry benchmark. Stated waits are illustrative calendar days between activities; actual times vary by estate, jurisdiction, client responsiveness, tax requirements and court capacity.
| Current-state activity | Touch time | Wait time |
|---|---|---|
| Initial instruction and conflict check | 45 min | 1 day |
| Asset and liability discovery | 120 min | 10 days |
| Will review and route assessment | 60 min | 2 days |
| Affidavit drafting | 120 min | 1 day |
| Client review and signature | 30 min | 5 days |
| Lodgement with the court | 45 min | 0.5 day |
| Court processing | 30 min | 14 days |
| Grant received and recorded | 15 min | 0.5 day |
| Notifications to institutions | 60 min | 3 days |
| Asset collection and liability settlement | 120 min | 7 days |
| Distribution to beneficiaries | 90 min | 3 days |
| File closure | 30 min | 1 day |
| Total | 765 min (12.75 hr) | 48 days |
Adding the 12.75 hours of active work to the 48 calendar days of waiting gives approximately 48.5 days of lead time. In the example, 600 minutes are assessed as value-adding legal, verification or client work; 165 minutes are avoidable rework, duplicate handling or status chasing. Using PCE = value-adding touch time ÷ total lead time, process cycle efficiency is approximately 0.86% (600 ÷ 69,840 minutes). This is a flow measure, not a score of legal quality. Court processing or other legally required elapsed time may be outside the firm’s control.
This view makes queues concrete: client signatures wait five days, institutional responses account for much of asset discovery, and the court queue is the largest single wait in this example. It also helps identify approval checkpoints that protect quality but can become bottlenecks when files wait for serial reviews or an unavailable approver. Legal Project Management U.K. describes VSM as a way to map communications, process steps and timelines, including the difference between lead time and active work (current-state mapping for legal teams).
3. Connect the eight wastes to probate work
Use DOWNTIME to examine non-value-adding activity without dismissing necessary legal safeguards:
- Defects: affidavit forms rejected for missing details, signatures or supporting evidence. Queensland Courts’ grant application troubleshooting guide illustrates jurisdiction-specific issues that can trigger corrections.
- Overproduction: unnecessary or duplicate correspondence sent before a complete document request is assembled.
- Waiting: delays for client signatures, third-party institution responses, internal approvals or court processing.
- Non-utilised talent: senior lawyers spending substantial time on routine administration that could be handled through controlled standard work.
- Transportation: documents and information passed between inboxes, systems or teams without a clear owner or single source of truth.
- Inventory: open files accumulating while they await client signatures or missing third-party information.
- Motion: repeated searching, retrieval and re-opening of files to answer status questions.
- Extra processing: re-keying the same estate details into multiple forms, trackers and messages.
4. Design a future-state flow
A future state should reduce avoidable handoffs while retaining appropriate legal review and clear exception routes. For standard matters, design around a complete, verified matter record and a visible next action:
Instruction and conflict check → structured asset and liability discovery in parallel → will and route review → checklist-led affidavit drafting → client review and digital signature where permitted → completeness and risk-based quality gate → court lodgement → court processing and tracked exceptions → grant received → coordinated notifications and asset collection → distribution → reconciled closure.
Practical changes include:
- Use standard matter templates and a defined intake and document checklist, tailored to jurisdiction and matter type.
- Run asset and liability enquiries in parallel where appropriate, with an owner, due date and escalation trigger for each response.
- Capture verified information once and populate approved documents from the matter record.
- Use digital signature only where legally and procedurally permitted; give clients clear signing instructions and a single document pack.
- Display matter stage, age, owner and next action on a daily status board. Escalate stalled items based on agreed thresholds.
- Route unusual wills, tax uncertainty, disputes and court requisitions through a named exception path, not the routine queue.
Capacity and takt time
Suppose four fee earners have 480 hours of net available processing time per month and the team completes 24 matters monthly. Takt time, the available work time divided by customer demand, is:
28,800 minutes ÷ 24 matters = 1,200 minutes of available team capacity per matter.
This is a capacity-planning pace, not a promise that each grant will be issued in 1,200 minutes. Compare demand and available capacity by matter type, and separate firm-controlled work from external waits.
5. Compare performance and sequence kaizen
The targets below are proposed pilot goals for this fictional team, to be tested against its own baseline. Segment results by matter complexity and avoid interpreting a faster average as success if quality or client outcomes worsen.
| Measure | Current example | 90-day target |
|---|---|---|
| Lead time, instruction to file closure | 48.5 days | 32 days |
| Touch time per matter | 765 min | 650 min |
| Process cycle efficiency | 0.86% | 1.30% |
| First-time-right court application rate | 68% | 90% |
| Open matters per fee earner | 18 | 12 |
| WIP aged over 60 days | 22% | 8% |
| On-time completion against agreed milestones | 72% | 90% |
| Rework hours per matter | 2.75 hr | 1.0 hr |
Implement in measured waves:
- Days 1–30, establish the baseline: Map 20–30 representative files; confirm definitions and jurisdictional controls; code delays and rework reasons. Owner: probate team lead with a process analyst. Target: timestamp data captured for at least 90% of pilot matters and a ranked list of the top three delay causes.
- Days 31–60, pilot standard work: Introduce matter templates, checklists, a daily status board and escalation triggers for one standard matter type. Owner: supervising solicitor and administrative lead. Target: at least 80% checklist use and a 20% reduction in preventable rework minutes from baseline.
- Days 61–90, verify and sustain: Compare the pilot with baseline, review rejected or returned applications, adjust the workflow, then decide whether to expand. Owner: practice manager with legal-risk oversight. Target: move toward the table’s first-time-right, WIP-ageing and on-time completion goals without weakening required review.
