I have always considered standstill agreements inappropriate in the context of a claim under the  Inheritance (Provision for Family and Dependants) Act 1975.  By entering a standstill agreement a defendant effectively promises not to put in a limitation defence if the claim is filed beyond the limitation deadline.   But the defendant facing an Inheritance Act claim cannot promise to allow the filing of a late claim because it is a matter for the court to give permission under the provisions of the Inheritance  Act, not a matter of limitation. 

Justice Mostyn's comments on the irrelevance of a standstill agreement in this context only highlights the position of the law rather than setting a precedent. 

Solicitors should be wary of advising clients with a claim under the Inheritance Act to enter a standstill agreement as it exposes them to the risk of a negligence claim should the client be denied permission to file their claim after the six month deadline.
