I am sorry but all this phrase means is that the person OWNS the house/car/other asset.
Married, living together, whatever. If the documents relating to an asset (e.g.property) is in your spouse/partner's 'name' THEY own it and not you.
Just feel that the phrase 'in his/her name' gives people a false sense of security in that they somehow own an asset that is NOT legally theirs.
Is it not misleading?
