If you die here, they put you right in the ground so you better make sure you’re dead.
If you are particular about WHERE they put you in the ground or IF they put you in the ground (instead of in, say, an urn), you want to make those arrangements beforehand.
For almost everything you do here, you have to use a lawyer. Finding a good trustworthy reasonably-priced attorney is a critical item. Talk to plenty. Take everyone’s suggestion and meet with that person. It’s critical.
And, if your Spanish is fledgling, work with an attorney that speaks very good English. Not halting: you want fluent. One word mis-translated can make ALL the difference in the world.
