In New York, the concept of "finders, keepers" does not hold legal ground. The law regarding found property in New York is governed by the state's Abandoned Property Law. This law outlines the steps that must be taken when finding lost property and the rights and responsibilities of both the finder and the rightful owner.

According to the Abandoned Property Law, a person who finds lost property must make reasonable efforts to locate and return the property to its rightful owner. This includes taking steps such as:

- Making a reasonable attempt to identify the owner of the property

- Making a public announcement of the found property

- Holding the property for a reasonable amount of time to give the owner an opportunity to claim it

If the owner of the lost property cannot be located within the specified timeframe, the finder is required to turn the property over to the local police department or the county treasurer's office. The property will then be held for a certain period of time, during which the owner can still claim it. If the owner does not come forward within that time, the property may be sold or otherwise disposed of according to the law.

It's important to note that there are some exceptions to the general rule. For example, if the found property is considered abandoned or has no apparent value, the finder may have certain rights to keep the property. However, these exceptions are limited and it's always advisable to follow the requirements outlined in the Abandoned Property Law to avoid any legal complications.
