Does getting married cancel my will?

Yes. Marriage or entering a civil partnership automatically revokes an existing will, unless the will was expressly made in contemplation of that specific marriage. If you are about to marry, either make your will after the ceremony or make it expressly in contemplation of the marriage, naming your intended spouse.

What is a codicil and when should I use one?

A codicil is a separate amendment document that must be signed and witnessed exactly like a will — two witnesses, same ceremony. It suits only tiny changes (a new executor address, a small extra gift). For anything significant, a fresh will that revokes the old one is cleaner and less dispute-prone.

Can I just cross things out and write on my will?

No. Alterations made after signing are not valid unless the amendment itself is signed and witnessed like a will — and messy handwritten changes are a classic ground for disputes. Never amend a signed will by hand; make a new one and destroy the old.

How often should I update my will?

After every big life change: marriage (which cancels the will automatically), divorce, a legal name change, a new child or grandchild, a death among your beneficiaries or executors, moving house, or a significant change in what you own. A five-minute review once a year is a good habit.

I changed my name — do I need a new will?

A name change does not cancel a will the way marriage usually does, but a will in your old name slows probate. Finish the deed poll and ID updates (we do not sell deed polls — Instant Deed Poll at instantdeedpoll.co.uk is a separate service), then use a free SwiftWill update and re-sign in your current name.

How do free lifetime updates work with SwiftWill?

Log back in with your email, update your answers, and download a fresh will instantly — free, forever. Print it, sign it with two witnesses, and destroy the old signed original. The new will's revocation clause automatically cancels every earlier will.

Changing Your Will: Codicil vs New Will (2026)

How to change or update your will

Quick answer

For anything significant, making a fresh will that revokes the old one is cleaner than a codicil — and with SwiftWill, updates are free for life: re-open the interview, regenerate, re-print and re-sign with two witnesses. Remember: marriage automatically cancels an existing will unless it was made in contemplation of that marriage.

Two life events change your will whether you like it or not

Marriage revokes. Getting married or entering a civil partnership automatically cancels any will you already have, unless that will was expressly made in contemplation of that specific marriage — see gov.uk/make-will. Marry without a new will and the intestacy rules decide everything.

Divorce amends by default. Divorce or dissolution does not revoke the will, but treats your ex-spouse or ex-civil partner as having died before you: gifts to them lapse, and any appointment of them as executor lapses. The rest of the will stands — which is rarely exactly what you would have chosen.

Codicil vs a fresh will

Codicil vs making a new will
Codicil	Fresh will
A separate amendment document kept with the will	One clean document that revokes all earlier wills and codicils

When to update: the checklist

Marriage or civil partnership (your old will is already cancelled)
Divorce or dissolution
A legal name change — finish the deed poll and ID updates first (SwiftWill does not sell deed polls; for an England and Wales document see Instant Deed Poll), then remake the will in your current name
A new child or grandchild
A beneficiary, executor or guardian dies or becomes unable to act
Buying or selling a home, or a big change in what you own
Your children reaching 18 — review guardianship and trust ages
