Unexpected Inheritance

"Chester: Where'd you get all that stuff!?

Timmy: Inheritance? Internet? I inherited the internet!"

- Fairly Oddparents

News of a death in the family is rarely well received, especially when its someone who cares very deeply for you. So deeply, in fact, that they have left you with a massive inheritance; but apparently not so much that they ever bother to get to meet you in person. This benevolent but reclusive relative you couldn't pick out of a police lineup (and trust us, this is something of a Plot Point) is usually an aunt or uncle, grandparent, great aunt or uncle, or related so remotely as to give a team of forensic genealogists weeks of work to find a direct connection.

The inheritance might be wads of cash, a lovely piece of land, and/or a set of family memorabilia. Depending on whether or not your relative was a benevolent Anonymous Benefactor is whether the money is tainted with the blood of innocents, the land contains a Haunted House built on an Indian Burial Ground, and whether the family memorabilia is something beneficial like an Ancestral Weapon or Protective Charm, or a higly cursed Evil Weapon or Artifact of Death.

In the middle of the road, the inheritance may be a Secret Legacy they are duty bound to follow, but which is nonetheless Blessed with Suck. Sometimes, there's a problematic condition you have to fulfill before receiving the inheritance.

One thing that tends to crop up is that the dead relative was alive all along and was pretending to be dead in order to pass on their inheritance. In these cases, the inheritor not recognizing their relative may allow them to be in close proximity by wearing little more than a Paper-Thin Disguise.

Compare Passed Over Inheritance and Game Between Heirs. In this trope, you do not have to worry about other heirs.

All Pitheco would inherit was the sum of twenty bucks (still on the marriage condition). The marriage was called off, much to Tooga's dismay.

 * The Simpsons features a couple of these:
 * In "Selma's Choice" Great-Aunt Gladys dies although nobody inherits anything of any real value beyond Jub-Jub the Iguana. Instead the funeral and will serve more to spoil the trip to Duff Gardens and allow Selma to inherit an increased sense of loneliness and isolation. YAY!
 * Played straight with an inversion in "Bart the Fink" when the Simpsons are required to spend the night in a supposedly haunted house (subverting the cliched plot when it turns out to be much more pleasant than their own) in order to collect the vast sum bequeathed to them by Great-Aunt Hortense. Until they find out that they missed the part where they only actually get $100 each while the rest goes to Ann Landers.
 * The Family Guy episode "Peter, Peter Caviar Eater" centers around Lois' Aunt Marguerite dying and the Griffins inheriting her opulant Newport manor.

 * One Scooby Doo episode centered around a member of the gang getting an unexpected inheritance worth millions - which turned out to be millions in Confederate currency, which was worthless (clearly they never thought of selling all that Civil War memorabilia to museums or other collectors). This came up again in one of the feature-length episodes.
 * One Rocky and Bullwinkle episode had Bullwinkle as the heir to the Earl of Crankcase, requiring him to spend a week inside the family manor before inheriting a 1 million pound note. At the end of the week it turns out that he isn't the rightful heir after all, and the actual heirs learn to their dismay that the note is a promissory note, and that they are now obliged to repay the late Earl's debts.
 * Another story arc had Bullwinkle inherit a mine from his Uncle Dewlap. The mine turned out to be in a mountain that floated miles overhead, because the mine was the only source of the anti-gravity metal Upsidasium.
 * While not strictly adhering to the trope (in that the deceased in question isn't a family member, but rather the leader of a rival gang), Batman: The Animated Series has one in 'Joker's Millions', in which the Joker, particularly down on his luck in terms of cash at the time, inherits $250 million from King Barlowe, a crime boss with whom he had shared a mutual hatred.
 * One Punkin Puss And Mushmouse episode featured Mushmouse inheriting one million pounds from a British uncle. Punkin Puss spent most of the episode trying to be on his good graces because of the inheritance until he and Mushmouse learned it consisted not of pounds as the British currency but one million pounds of cheese.
 * The premise of the short-lived cartoon Monster Farm (not Rancher) involved a young man inheriting said farm from a great uncle Karloff.
