children (35 years old) will not work or study

[apibeeman]

My wife has a married daughter both her and her Chinese husband are 35 years old they don't study, work or in fact do anything useful, get up after mid day, play computer games and sponge off us, for last two and a half years. I have had enough, is that unreasonable.

Are they actually tortoises? Who've relocated due to climate change?

Sounds like a total troll, but I'll bite. Get them out the house for the day. Have movers take their stuff to a storage unit. Change the house locks. Hand them the keys to their storage unit and let the bad tempered daughter wail and cry outside for as long as she wants. She's bound to be upset when the gravy train runs out.

I sympathise OP. My 90 year old DM is in a similar situation with my sister, her husband and their 2 children. They have their own property abroad and my DM feels intimidated by them, but won't actually commit to having them removed. My sister is 55!

That makes me feel better, knowing there are others in the same situation. I am afraid the only way out is to be nasty.

I don't think you need be nasty.

You do however need to be firm.

You and your wife need to agree a plan. Give them notice that the daughters allowance will be reduced/stopped in 3 months time, during which they will be expected to find work.

They then have another 3 months to find their own accommodation in order to be independent.

At any point if the daughter flys of the handle the response is that this entitled behaviour is exactly why she needs to gain her independence. She can accept the "deal" with good grace or you will in fact accelerate the process of her temper continues to dominate her behaviour.

If your wife won't agree to that then I think you need to decide if you can life the rest of your life this way or if you want to travel another road....

I also like the idea of moving to a smaller property that can't house them

Well what ever I do has to be quick. The mother has just informed me that they are trying to make a baby.

It'll be the emotional blackmail next, to your wife. 'You won't see your grandchild, if you make us leave'.
