Back at 2006 my mother who was living abroad sent money to her sister and husband to start a business.There were no legalities or written documents except for receipts from a remittance service that she did sent money.She also didn't get any shares/money when the business started getting profits, since me and my mother live abroad we were just happy that our family in the Philippines are doing well.
Now my mother and her sister had a falling out (mostly because her sister refused to help her pay for their father's weekly dialysis), so she wants to pull out her name in everything her sister used or at least get her monthly share on the business.
Also, my aunt used my picture from 2008 until today to advertise the business and use it in tarpaulins/billboards.We also didn't have any signed documents nor I got any "talent fee" since its family.
Is there any way me and my mother can get anything? We just really need help on my grandfather's expensive dialysis and we felt we got betrayed by my aunt.
Please help us.
P.S. The business my aunt and uncle started has at least 20 franchises all over the country now.
Thank you.
