You would do well to find an attorney to best advise you on this matter. There are simply too many issues that fall into too many categories.
What we do offer as some suggestions and guidelines for you to explore are:
1. Of course you can pay yourself back for any expenses you incur on her mother's behalf - keep records because Elder Financial Abuse is a serious crime.
2. You need to understand Nevada Elder Services and Medicaid (they are not the same thing) and what options are availabe to your mother - some states do not included A&A when tabulating income for A&A, but remember, you can not assume what amount of the payment is A&A, you must ask the VA for a letter in writing, some states have programs where a family member providing care can get reimbursed by the state for a certain number of hours, some states provide Home Health Aids for a certain number of hours if you meet their financial criteria - obviously, it is important to work with someone who understands the rules in Nevada - and that someone will likely be a team of people, not just the Elder Law Attorney. Elder Services is who you should call for services offered by the state.
3. Look on the NAELA (National Acedemy of Elder Law Attorneys) website for a Nevada Elder Law Attorney https://naela.ebiz.uapps.net/solutionsite/Default.aspx?tabid=148
. There are many listed.
Hope this helps with some of the decisions you are faced with and we wish you the best of luck.
