How can personal representatives deal with an estate?

By law, Land Registry always has to assume that personal representatives are acting within their powers. The Land Registry is not empowered to investigate whether any transfer is in accordance with a will.

Personal representatives might become the registered owners in their capacity as personal representatives.

Personal  representatives could transfer the property to the beneficiary (or to the executor as trustee) by a deed called an assent (they can do this without being registered as owners first).
