Inherited Retirment (IRA) Account (non-spouse)

When my mother passed she left an IRA account that got split up among the kids. I just read an article with the sentence: "If you leave retirement money to your kids or anyone other than your spouse, they’re typically required to empty the accounts by the end of the 10th year following the year of your death."

Is this correct? It is the first time I have ever come across this requirement in the (almost!) 10 years since her death.
