This is a plot point in various SF works. For example, in the Honor Harrington books by David Weber, the Manticore system colonists traveled to their target a couple hundred years in hibernation. But as it was likely propulsion technology will advance before they reach their destination, they also left part of their money in a trust fund back on Earth, to make sure the Manticore system won't get squatted in the meantime. This proved to be a sound idea, as practical FTL drives have been invented after the colony ship has departed and they have been greeted by the Manticore Trust navy upon arrival, that has secured the system a couple years earlier, arriving by the newfangled hyper drive. :)
