Contracts concerning succession.
A contract to make a will or devise, or not to revoke a will or devise, or to die intestate, if executed after January 1, 1977, can be established only by (1) provisions of a will stating material provisions of the contract; (2) an express reference in a will to a contract and extrinsic evidence proving the terms of the contract; or (3) a writing signed by the decedent evidencing the contract. The execution of a joint will or mutual wills does not create a presumption of a contract not to revoke the will or wills.

For the purposes of this section, an oral contract is "executed" at such time as the parties become bound to each other for the performance of the terms of the agreement. In re Estate of Nicholson, 211 Neb. 805, 320 N.W.2d 739 (1982).
