My aunt is pretty wealthy and has offered to by my cousin a house (worth approx 250k) for his 30th birthday, provided he pays the stamp duty etc himself.
Cousin has been with his long term girlfriend for about 6 years but they aren't married and don't have children(unsure whether it's on the cards) and my aunt is buying the house for my cousin (in cash, no mortgage) on the condition that is is in his name only . Cousin and girlfriend currently live together and split rent and bills and the plan is for them both to move into the new house and just split bills (as there will be no rent/mortgage). Cousins gf has thrown a bit of a paddy that she's "not allowed" to be on the deeds of the house, now I can see that she wants some security but AIBU to think it's a bit grabby to want half of it? She's argued that technically cousin hasn't "contributed" either and that as his long term partner she should share in his windfall - she thinks my aunt IBVU. (My aunt does understand that if they marry then the girlfriend will be entitled to half and she's fine with this, just doesn't want to hand over half to a "partner").
On the other hand I can sort of see girlfriend's side so I suggested to my cousin that they both save up and jointly buy a buy to let which will give her some security, since they are now both benefitting from being rent free!
