Dennis Hopper's 9-Year-Old Daughter -- Congrats, You Inherited $3 Mil

Dennis Hopper's 9-year-old daughter inherited $2.85 million from her dad's estate ... despite the fact her parents were entangled in a nasty divorce battle at the time of his death.

If you recall ... Hopper's estranged wife Victoria Duffy fought tooth and nail for a stake in her late husband's estate ... but ultimately came up dry.

Now, according to legal docs obtained by TMZ ... Dennis made sure their 9-year-old daughter will be taken care of ... leaving her $2.25 million in cash plus $600,000 worth of property ... all of which has been placed in a trust.

In the court docs, Hopper's people make it clear ... Victoria, who was married to Hopper for 13 years but received zilch thanks to an iron-clad pre nup -- shall have NO control whatsoever over the money in her daughter's trust.

If you recall ... Hopper died in 2010, before his acrimonious divorce with Victoria could be finalized.
