My question today is, after having a mild stroke, how long should one wait before making major life decisions? It's only been one week.

I doubt, if first car financing, the daughter realizes that her father would be held responsible if she defaults on the loan. She just wants a car.

His answer is no. You may want to tell her that she is upsetting Dad and needs to let it go.

Janz, how old is his daughter? Not that it relieves her of any moral responsibility for what she's doing to him... Since your profile says your partner is only 50, I'm guessing his daughter is over 18 to early 20s-ish. I've co-signed an auto loan for my son, and a student loan for another, based on my faith that they are responsible human beings. So I'm not bothered that she is seeking a co-signer (you haven't given us all the details) BUT her persistence when he is trying to recover and has already said no once is unacceptable. My guess is that's the family culture that has been in place all along. He may have a full recovery (and you also haven't told us his current health condition) so he can choose to help her but not at this moment. A lot depends on whether he has enough financial resources and good healthcare coverage for his current needs. Has his stroke affected his ability to work? His cognitive abilities? He needs to fend her off with his own mouth. Your profile says you are his partner, so not married I'm assuming -- I'm only bringing this up because normally the wise priority is spouse over children so: do you have comingled funds with him? If you do then I think you should have a say in this decision. If not, then you may have to stand by and watch the train wreck. I wish you all the best in moving through his recovery together!

Your partner is only 50 and has had two strokes. When was his first stroke? I ask because stroke is what's killing many younger people with COVID19.

Louis is under no obligation to answer his daughter's calls. When she calls, he could text back "No, I am not cosigning a vehicle" and leave it at that.

I would have a chat with Louis about establishing healthy boundaries with this daughter. Explain that you see he's nervous and shakes. Ask him to consider letting her calls go to voicemail.

Is the girl's mother around? Might you have a woman-to-woman chat with her mother to bring this girl around to reality?

Old enough to own and drive a car??

OLD ENOUGH TO PAY FOR IT!

You are doing a good job of caring for this man, and I hope you feel perfectly comfortable.

Frankly, I don’t even know if it would be legal.what she want CERTAINLY IS NOT MORAL.

Hope he continues to take care of himself, rest and do what his doctors tell him to do, and IGNORE SELFISH REQUESTS.

Please take good care of yourself, too.

She has to stop. She has to take no for an answer. Frankly, she can consider herself fortunate if he feels like reconsidering later but the stroke isn't really relevant: it's pretty much a case of no means no.

Had he made her a promise about the vehicle that she had relied on in good faith, or anything like that? Otherwise her persistence is unforgivable.

This sounds like someone that I would NEVER co-sign a loan for, nor would I lend this person money (give maybe cuz ya know it is never going to be repaid..and I would not give them money either)
This sounds like someone not to be trusted at all.
It also sounds like he can not handle the stress of these calls and dealing with her. I would not take her calls id she continues this way.
If nothing else would it frighten her back into reality if you told her that you would report her for attempting financial elder abuse? If you have an Elder Care Attorney you could bring this up with the lawyer. (If you don't have an Elder Care Attorney you might want to consult with one for a variety of reasons)

You need to deal with the stepdaughter. Tell her that her father has already told her he won’t co-sign a loan for her. At this point, his cognitive ability to sign takes a backseat to the fact that he’s told her no. She is harassing him. Make sure he goes nowhere with her alone where he could be tricked by her into signing something.
