Some cost for sure. See this from Kevin Bell Trust : While the cost can be a major barrier for most families who have to repatriate a loved one's body from abroad – costs per repatriation can cost up to £12,000 (€14,000) depending on the circumstances of the death, local charges and hospital release costs – there is also a lot of “red tape”.
But some families like a grave stone and a grave I guess. It beats maybe telling the kids/ mother wife/.. well 4 people turned up at your daddys funeral and we not sure where the ashes are now. Some drunken expat threw them in the pattaya bay sinkhole 😞
