When Bob Alberti's cousins learned that his grandmother had died without a will, they descended on the house to take what they wanted -- even unwrapping unmarked Christmas presents. It gave him a firsthand look at how greedy family members can take advantage when there isn't a plan in place.
"I learned a lasting lesson then: Do your family a favor and make a will," Alberti, of Minneapolis, said of his childhood experience.
As the nation's 76 million baby boomers age, more families are being faced with how to divide personal belongings. Adding to the challenge: There are more family members in the mix because of changing family dynamics, most often because of divorce.
Wills often cover the transfer of cash, property and stock, but often skip over who gets household possessions. That can cause emotions to run high over who gets Grandma's pearl necklace or Dad's fishing pole. Disagreements over who gets what can lead to bawling and brawling between siblings that can scar relationships forever.
"How often it happens is anecdotal, but too often siblings fight over common possessions and never speak to each other again," said Marlene Stum, a University of Minnesota professor who helped write a guide called "Who Gets Grandma's Yellow Pie Plate?" "When an inheritance is involved, rivalries play out."
While experts say planning can help, sometimes it's not enough to stave off greed and hurt feelings.
"It's important for families to talk, because there are always hidden agendas," said Stum. There is often a "mom loved you best" assumption lying in the weeds.
To avoid this problem, families need to establish goals and decide what's fair. Otherwise, laying claim to an ordinary candy dish can become symbolic of someone trying to right all those childhood wrongs, she said.
