How to get a ghost back to her beloved family?

Well...Becca Clarke had a potluck event in her apartment (she lives in the new world that came with For Rent) and invited all her neighbors, and the event went fab. Becca reached golden status and everyone was very happy about it. Including the unfortunate Lien Sadya, who was so happy/hysterical that she died very dead. Becca did try to plead with Mr. Grim but nope.

So now Becca has a nice golden looking urn on top of her bookcase and the Grim Reaper watching her tv. She also has no idea what to do with Lien's remains.

Now I do not want to loose this Sim to the netherworld but I also don't want her tied to Becca for all eternity so what can Becca do to return the urn back upstairs so Lien can live her...well undead life with her beloved family?

Now I know that I can make the ghost playable by moving her in with Becca (either with cheats or no cheat) and then have her move back in with her family but I like to have her unplayable for a little while and come out of her urn in her family home before I decide what to do with her. Either make her playable and maybe later have her come back to life or release her spirit to the netherworld and have her husband move on.

So I was wondering if I could have Becca visit upstairs with the urn and leave it there somewhere? I mean, is the urn considered Becca's property? Or does the property of the urn go to the household where the urn is left and have that household be able to decide what to do with the remains? Maybe able to put the urn in their inventory and move her to a graveyard?

I have only left urns on community lots like the generic ones where I have a graveyards, never on residental lots.
