Robin Williams' widow, Susan Schneider Williams, says she had no choice but to take the comedian's three children to court over his estate last year.

"I was forced into it, basically," Williams, 51, told ABC News in part two of an interview that ran on "Good Morning America" Wednesday. She recalled that, "Two and a half weeks after Robin had left, I was still in shock. And not back in our home," adding, "I was told that I might not be able to keep our wedding gifts, that in fact, 'While you're out of the house . . . we need to come in and take everything out.' " The children disputed this in court documents filed in January.

Susan Williams, who was together with Robin Williams for seven years and married for nearly three at the time of his death at age 63 in August 2014, said she was told that, "Eventually, once we've gone through it all, you can . . . tell us which items are yours. And we'll decide whether or not that's true."

The two sides reached an out-of-court settlement in early October. The accord was "basically what my husband wanted," Susan Williams told ABC News, "which was just that I could live in the home until I die."
