My wife's sister who is about 52 needs to be committed--at least for observation. She has attempted suicide twice, has gone off her meds, is about to be evicted and she will join the people roaming the street with a shopping cart if something isn't done. She lives in Texas.

How can her sisters and brother force her into confined hospitalization before it is too late?

You need to her physician to sing the papers, then get a court to order commitment.
