While my mom is only in her 60's right now, my dad has already passed and I have NO doubt that when the time comes to take care of my mom, I will get little to no help from my 4 siblings. I think often the burden falls to one child and it would be in your best interest to get power of attorney and just do what you need to do.
It's not worth fighting with your sister when she clearly doesn't want to contribute much. It will just cause you more stress and as a result, more stress on your dad.
When all is said and done, you will sleep well at night knowing you did all you could for your dad. Your sister will be the one who has to live with herself knowing that she didn't care enough to be there for him. |
