Thanks for your patience and enquiry.
Inheritance is treated differently based on what stage in separation you are in.
If you were to separate now and enter into a clean break order, then your inheritance would not be a part of the matrimonial pot. So your husband could not in the future claim an entitlement to your inheritance.
If for example you were to separate and not have an order put in place with respect to finances by way of the clean break order, then your husband could in the future make a financial claim against you.
It is recommended therefore that if you were to separate now that you ensure that an order is put in place with respect to your finances. Future inheritance are not considered part of matrimonial assets.
What if you were to get the inheritance now? It is not automatic that it will be considered matrimonial asset. Whether this is the case, depends largely on how the asset was treated by you. For example, if it was put into a joint account or used for the maintenance of the joint home or used jointly by yourself and your husband then it would be treated as a matrimonial asset. However, if the inheritance is kept separately then it could be argued that it is not a matrimonial asset.
