URGENT!! Need no cost legal advice for widow who's spouse committed suicide;inlaws have own interests not hers

Please help....My good friend who's husband committed suicide on sept 10, 2007. There's real and personal property. No will. The inlaws are pushy, self-serving and disrespectful of her feelings & rights. She was physically and mentally abused prior to his suicide. She just wants what is rightfully hers and to be treated fairly and respect her rights. She has and has had no income thru the entire marriage, is disabled and is a having hard time, as she is unsure as to exactly what is and isnt suppose to happening. Petrified she may get booted out of the home she and her husband shared. Knowlege and info would be priceless, not knowing is the majority of the fear. Please help asap with any info, referral and/or advice...thanks
