'unless there is good reason to the contrary'
“The parties' matrimonial home, even if this was brought into the marriage at the outset by one of the parties, usually has a central place in any marriage. So it should normally be treated as matrimonial property for this purpose. As already noted, in principle the entitlement of each party to a share of the matrimonial property is the same however long or short the marriage may have been.”
“I have not come across any case law to suggest that it is not possible to have multiple FMHs, or that property once matrimonialised can then un-matrimonialise.”
“…the court will typically conclude that the former matrimonial home should be shared equally although this is not inevitable as shown by cases such as FB v PS[2015] EWHC 297 ...In its evaluation of all the relevant factors… it would be perverse if the court could not decide that the non-matrimonial source, in whole or in part, of an asset treated as matrimonial property could not justify an other than equal division”
