I asked yesterday about filing alone - my wife has a 9plex apartment complex LLP with her brother''s and sister; I am NOT a member. Does that affect me

The issue will not be the asset but rather the household income.  What cash, if any, does the LLP throw off?Her independent investments are irrelevant to you for most purposes.  The bankruptcy of a partner in an LLP can be an act of dissolution, which is a possible complication, so it would be good if your wife does not join you in your petition.
