I agree, you should talk to an attorney. A few $ now could save you a ton of heartache later. This is not something to be cheap about. I say this as the DD of a woman who made her wishes crystal clear (everything split equally among her 4 kids), but then died of dementia. If there's a will an additional assets (I suspect another bank account), we have no clue where they might be.
As far as gifting goes--this might be a real good idea, but I would again run it by an attorney to make sure everything is on the up and up. To avoid the $11k limit, your mom could "gift" you, say 15 points this year, then 15 points again next year, etc. She also gets a certain exclusion, so if she gave you more than $11k's worth in one year, she would have to file saying this was part of her exclusion. Then, she would have that much less of an exclusion upon her death. Does that make sense? Estate planning does get tricky, and especialy now when the exclusion rates are changing every year, vanish in 2010, and then reappear in 2011. really, I can't emphasize enough the value of a good estate attorney.
