Nielson-Jones v Fedden [1975] Ch 222 is an English land law case, concerning co-ownership of land: specifically whether a settlement agreement between spouses or memorandum, vaguely worded amounted to "words of severance" as effective under section 36(2) Law of Property Act 1925.

After a breakup in the relationship a memorandum was agreed to grant the husband discretion to sell the house.

Walton J held this dealt with use of land, not ownership of proceeds of sale, and so severance was not effective.

The memo was insufficient to sever the joint tenancy under the Law of Property Act 1925, section 36(2) because it dealt with use and not ownership of the house/sale proceeds.

Also, no (firm) agreement could be drawn from the parties’ ongoing negotiations.
