From my past experience, transfer it now when you parent is still alive. It is very hard to gauge human characters, you will never know if your own brother will become a scum after your parent not around.

The argument will appear when your parent no longer around. Eliminate all the possibilities for that argument to happen when you can and able to do it. You can avoid unnecessary family feud & save a blood relationship.

Transfer now can minimize the seriousness of the issue. Unless TS become char siew & kick the parent out after that, then nothing can be said.

Normally 2 names the most , even 2 names also are not encourage. Go single name enough. Those name not in the title, normally yes - commercial compensation by the name in the title.

Transfer now, what foreseeable problems? The most only kena caveat the title by the sibling boh song after the parent not around. If caveat, let them caveat la, after 5 year the caveat will auto be dropped. Let them go caveat every 5 years at the land office.
