After you sign
Your will is only the start.
Every Trusted Hands will is wired into the same legacy system: executors notified automatically, documents stored alongside the will, and a secure portal that unlocks for your executors when the time comes.
1. You choose your executor(s)
Appoint up to four executors as you build your will, plus named substitutes in case your first choice can't act. Friend, family member or professional - your call.
2. They're emailed automatically
The moment you finalise your will, each executor receives a calm, clear email explaining they've been appointed and what happens next. They see no documents while you're alive.
3. Family Vault stays with you
Add insurance policies, deeds, identity papers, financial accounts, funeral wishes and letters of wishes to your encrypted vault. You control what's shareable and what stays private.
4. Vault unlocks when the time comes
After a death is confirmed, your executor portal unlocks. They find the will, the Executor Pack, a live checklist and the documents you chose to share - all in one place. No drawer-rifling.

Build will + LPA togetherWhen mutual wills are right
A mutual will agreement is most often used by:
- Blended families where each partner has children from a previous relationship and wants certainty those children will inherit
- Couples who agree firmly on where the combined estate must ultimately go
- Anyone wanting protection against the survivor unilaterally changing the plan after the first death
Important to understand
Mutual wills are powerful but restrictive. The binding agreement means the survivor cannot rewrite their will after the first death. The builder walks you through the binding-attestation step so you understand exactly what you are committing to before signing.

Frequently asked
How are mutual wills different from mirror? Mirror wills can each be changed independently. Mutual wills are bound by an agreement - once one of you dies, the survivor cannot change theirs.
Can the binding be removed? Only while both of you are alive and in agreement. After the first death, the surviving will is locked to the agreed terms.
