Even experienced will writers and estate planners can fall into recurring pitfalls that lead to disputes, delays or unhappy clients. This guide highlights common mistakes and practical steps to avoid them, helping you deliver reliable, compliant and well-documented wills and related estate planning documents.
Poorly recorded instructions and assumptions
One of the most frequent causes of later disputes is reliance on oral instructions or unrecorded assumptions about a client’s intentions. What seemed obvious during a meeting can be interpreted differently after the testator’s death.
- Record everything: Use your portal’s client notes and case files to capture why a provision exists, options discussed and any potential complications.
- Confirm in writing: Send a concise summary of instructions to the client and keep the confirmation in the file.
- Use templates wisely: Templates speed work but never replace tailored notes explaining why non-standard clauses were used.
Overlooking essential legal formalities
Wills must meet strict formalities to be valid. Small errors can render a will invalid or open it up to challenge.
- Witnessing: Ensure valid witnesses (capacity and disinterestedness) and that they sign in the correct order. Document the venue and date in the file.
- Capacity and understanding: Record your assessment of the testator’s capacity and understanding, including any professional involvement such as medical advice if capacity is uncertain.
- Attestation clauses: Include a clear attestation clause and store the final executed copy securely in your document storage.
Inadequate estate and asset checks
Failing to take a complete and accurate inventory of the client’s assets can lead to ineffective provisions—assets outside the will, incorrect beneficiary designations and unintended tax consequences.
- Comprehensive asset list: Capture property, bank accounts, pensions, life policies, digital assets and business interests in the client record.
- Check ownership and titles: Confirm how assets are held (jointly, tenants in common, trust-held) and whether beneficiary nominations override the will.
- Link to probate considerations: Consider whether property will require probate or specialized administration; resources such as https://probate-property.co.uk/ can be helpful reference material.
Failing to plan for incapacity and powers of attorney
Drafting a will without addressing incapacity leaves clients and families exposed. Lasting Powers of Attorney (LPAs) are a vital companion to wills and should be part of standard client conversations.
- Discuss LPAs early: Introduce Lasting Power of Attorney for health and property during estate planning meetings and record client decisions in the portal.
- Document referrals: If you do not prepare LPAs, document any referrals made and follow up to ensure the client has appropriate protections in place.
- Co-ordinate documents: Ensure the will and any powers of attorney are consistent, particularly where trustees or executors are also attorneys.
Ambiguous or impractical trust and gift provisions
Imprecise trust terms or impractical legacy instructions create administration headaches and may frustrate the testator’s intentions.
- Be specific: Define key terms (e.g. "maintenance", "education") and include reasonable ages or triggering events for distributions.
- Appoint robust trustees/executors: Record trustee skillsets, alternate choices and consider professional trustees where required by complexity.
- Practical administration: Ask how easy it will be to value, manage or sell assets left to a trust and record any advice given to the client.
Insufficient consideration of taxes and succession planning
Failure to consider inheritance tax (IHT), business relief or agricultural relief can result in unexpected tax bills for beneficiaries.
- Early tax review: Run a preliminary IHT check as part of the file opening and flag potential liabilities in client notes.
- Use planning tools: Use your portal’s planning features and knowledge base alongside specialist resources such as https://trustmarklaw.co.uk to ensure options are considered and recorded.
- Coordinate with advisers: Where clients have complex tax or business assets, formally document referrals to tax advisers or accountants and note any joint recommendations in the file.
Poor client communication and review processes
Clients change circumstances; wills age. Without regular review and clear communication you risk out-of-date documents and disappointed families.
- Set review reminders: Use dashboards and reporting tools to schedule periodic reviews or trigger reviews on life events (marriage, divorce, property sales).
- Explain limitations: Make clear what the will does and does not cover at the point of signing, and store client confirmations in the account record.
- Offer clear guidance on storage: Advise clients on secure storage and ensure the location of originals is recorded in your document management system.
