If it isn’t a tax fiddle then your parents have strange ideas about gifts and ownership
(A tax fiddle can mean anything that a would be taxpayer puts in place that means they avoid paying tax)
For all intents and purposes that house is no longer anything to do with either of your parents. Likewise the houses that your parents gifted to
So saying they can ask for them back at a later date could also involve mortgage fraud if any of your siblings move to a larger property and use the money raised from the sale of the house your parents gifted to them as a deposit
What happens if your siblings find themselves getting a divorce.
Even if the house is in your siblings name then it is marital property. How are they going to ask for a “gift” back if half of the money used to buy it has gone to someone who has no reason to pay it back
Your parents are acting like they are the best parents in the world gifting their children houses. However they still seem to think they own the gifts.
Which is the only explanation for the reason your mother decided to open up someone else’s house and install her sister and her bf in to live rent free because she knew better and it was her house afterall when you refused to agree to it.
Do your parents actually see any of you as adults? Or do they think they can move you like a chess piece when they want something
and you will comply because they see you all as small children playing house.
What if they want a house back. Where is that one sibling and their dc going to live? What if a sibling or all decide their parents can’t have “their” houses back?
Your mother could be prosecuted for something like this.
She has put herself on dodgy ground as ultimately she is responsible for the damage your aunt caused.
As your mother I presume has paid the insurance on the house I would like to see what she has put down when filling out forms, Like is the house occupied, If she has said yes on your behalf then you are going to have difficulty getting your aunt out.
You can’t argue your aunt is squatting if you know and agree on forms she is living there.
I don’t even think you could be covered for the damage
You all need to be a little smarter and get your stories straight because atm your aunt is playing you all like a fiddle because she knows your mother has cut corners and lied
There does seem to be a lot of lying
