SPRINGFIELD, N.H., SEPT. 27 -- Pierre S. (Pete)

du Pont IV, a candidate for the 1988 Republican

presidential nomination, and three cousins say they

believe they are legally entitled to $1.5 million

of an aunt's estate that has been awarded to four charities.

Lawyers for du Pont and his three cousins have

challenged a will left by Nancy Holcomb Anderson, who died in 1984. Manchester (Vt.) Probate Court Judge Ellen Maloney has ruled that the will, while ambig- uously worded, stated that the money should go to

four charities, including a humane society in Ver- mont.

The challenge centers on whether Anderson's intentions were correctly presented or whether the legal draftsman made a mistake.

"It's really a question here of carrying out the intent. Were the {aunt's} intentions thwarted by an error in the drafting of the will?" said du Pont's deputy campaign manager, Bob Perkins.

After a campaign appearance last Friday, du

Pont said contesting the will would not hurt his campaign.

"I think that anybody whose aunt left some money . . . and some lawyer walked in and said the will isn't right, would say, 'Hey, wait a minute.' I think everybody understands that," the former Delaware governor said.

Du Pont is a member of the family that founded the giant chemical company E.I. du Pont de Nemours & Co. He is the wealthiest of the presidential candidates, with assets of more than $6.3 million, according to financial disclosures he made last spring.

Perkins said du Pont wants the money in part to set up a trust for his children.
