Thanks for that information.
The inheritance received during the marriage could therefore be considered a marital asset.
It really does depend on what their needs are and how these can be met by the house that they own jointly, for example if he is able to buy her out of her share with a mortgage or vice versa.
It may be possible to offset any claim he has to the inheritance by 'doing a deal' on the split of the joint house asset.
It's also sometimes possible to argue that inheritance that comes late in they and post separation (though I appreciate they are living under the same roof they can still be classed as separated) should be excluded from a settlement, but it really does depend on how the other assets play out as to whether this is possible.
Pensions seem quite straightforward, if each has not had them for a long time they won't be worth much and should simply be retained individually.
Whether or not he has savings is important, as these would also be considered a joint asset.
So, he may have a claim, but this is difficult to be clear about without full financial disclosure and each party setting out what their expectations are. And as I said, it is possible to balance the books without him having had to take a share of her inheritance, by offsetting other assets.
I hope that this answers your question?
