What is the difference between joint tenants and tenants in common?
Joint tenants own the whole property together with no defined shares, and on death the survivor takes everything automatically, outside the will. Tenants in common each own a defined share, equal or otherwise, that passes under their will or intestacy. The legal title is held on trust in both cases; what differs is who owns the beneficial interest and what happens to it on death. Joint tenants or tenants in common covers the choice in full.
Severance moves you from the first column to the second. It does not change who can live in the property, who is liable on the mortgage, or who must sign to sell it.
| Joint tenants | Tenants in common | |
|---|---|---|
| Shares | None, you own the whole together | Defined: equal by default, or as a deed of trust records |
| On death | Survivor takes everything automatically | Your share passes under your will or intestacy |
| Can a will deal with it | No | Yes |
| On the register | No restriction | A Form A restriction |
| Selling after a death | Survivor sells alone | Survivor plus a second trustee to give a valid receipt |
| Right to occupy | Both owners | Both owners |
| Changing later | Sever to tenants in common, unilaterally | Back to joint tenants only by agreement of all owners |
Can I sever a joint tenancy without my co-owner agreeing?
Yes. Section 36(2) of the Law of Property Act 1925 lets any joint tenant sever by giving written notice to the others, and it takes effect on service without their consent. The co-owner cannot refuse it or undo it, and ignoring it makes no difference; they can only respond by making their own will. The notice must reach them, though, which is why service and its evidence matter. Section 196 of the same Act allows service by leaving the notice at the co-owner's last known abode or by registered post, and the notice is treated as served when it would ordinarily be delivered, even if the co-owner does not read it. The deeming in section 196(4) carries a proviso that matters: it applies only if the letter is not returned undelivered, so a notice that comes back in the post is not served and has to be served again by another route (checked 20 September 2026).
HM Land Registry then needs to know. Form SEV can be signed by both owners if you agree; if not, you sign alone and certify that notice was served, attaching the notice and the proof. Panel 7 of form SEV, edition 08/23, sets out what will do: the notice with a signed acknowledgement of receipt, or a certificate that it was served in accordance with the Act (checked 20 September 2026). The co-owner's permission is not needed. Whether the registry writes to them about the application is not something any published source states either way.
