I am on my mother's small savings account. Should I move the funds to my personal account before I seek guardianship?

No reason to complicate your life by moving the money. Just write checks from her account for her care.

Since you're already on your mother's account, you should have no problem paying her bills with that account while awaiting guardianship. I did exactly that with my dad's account, although I wasn't actually on his account, but shared financial and health DPOA with three of my siblings. Be careful to keep an exact record of every transaction involving your mother's account. Best wishes.

If you move funds before you are guardian it could be seen as conflict of interest or cause problems if you seek medicaid for her within 5 years of the transfer. Best to leave funds separate until it’s granted.
