Consultation on Adding a Second Owner (Joint Tenancy vs Tenancy in Common)
Property owners in the United Kingdom often face the need to make changes to the ownership structure, particularly when it comes to adding a second owner. This may be relevant for spouses, partners, family members or investors. The service is most often requested to obtain professional clarification of the differences between forms of joint ownership — joint tenancy and tenancy in common — and to choose the best option for registering the rights of the new co-owner, taking into account future tax, inheritance and financial consequences.

The service helps avoid unpredictable risks in the event of relationship breakdown, death of one of the owners or future sale of a share.
Correct Choice of Joint Ownership Form: Joint Tenancy or Tenancy in Common
One of the first decisions to be made before adding a second owner to the property title is the choice between ownership forms. This determines whether the share is inherited automatically or passed through succession, and what rights the parties will have in the future.
Solicitor’s actions:
- provides advice on the key differences between joint tenancy and tenancy in common;
- analyses the client’s situation in terms of family, financial and inheritance aspects;
- recommends the optimal form of ownership according to the client’s interests.

Outcome: the client receives a clear understanding of the legal consequences of each form of joint ownership and a reasoned recommendation on the most appropriate option.
Legal Registration of the Second Owner in the Property Title
After deciding on the form of joint ownership, it is important to correctly formalise the changes to the property title documents. This must be done in accordance with HM Land Registry requirements and the applicable tax regime.
Solicitor’s actions:
- checks the existing title deeds;
- prepares and submits TR1, JO or other required forms to HM Land Registry;
- sets the ownership form in the legal record — joint tenancy or tenancy in common;
- if necessary, prepares a Declaration of Trust or other supporting documents.

Outcome: the client has officially registered joint ownership of the property with properly documented rights of each co-owner.
Legal Consequences of Adding a Second Owner: Taxes, Inheritance, Liability
The form of joint ownership and the addition of a second owner may affect the parties’ obligations in tax, civil and inheritance matters. Understanding these consequences helps avoid unpleasant surprises in the future.
Solicitor’s actions:
- assesses the tax implications of adding a second owner (CGT, SDLT, IHT);
- provides recommendations on inheritance and possible rights to the share in case of death;
- analyses liability risks in case of debts of one of the co-owners.

Outcome: the client receives a complete picture of potential legal consequences and a clear understanding of how to minimise risks for themselves and their share in the property.
