A declaration of trust is a legal document that is used to set out the ownership of a property and the rights of the individuals involved. It is most commonly used in the UK when two or more people own a property together, such as in a joint tenancy or tenancy in common.

The declaration of trust outlines the ownership of the property, the rights of each individual involved, and the responsibilities of each party. It also sets out the rules for how the property should be managed, and how any profits or losses should be shared. A declaration of trust can be used to protect the interests of all parties involved in the property ownership.
