The anomalously named California Uniform Partnership Act of 1994 specifies when a partner in a general partnership "dissociates".  Cal. Corp. Code § 16601.  Upon dissociation, a general partner loses the right to participate in the management and conduct of the partnership business.  Cal. Corp. Code § 16603(1).   One would expect that the dissociated partner would also cease to be liable for a partnership obligation incurred after dissociation and that is what the act indeed provides in Subdivision (a) of Section 16703.  There is a significant exception, however,

Section 16703(b) provides that except for registered limited liability partnerships and foreign limited liability partnerships, a dissociated partner is liable as a partner to the other party in a transaction entered into by the partnership within two years after the partner's dissociation if at the time the transaction is entered into all of the following apply:

• The other party reasonably believed that the dissociated partner was then a partner;

• The other party did not have notice of the partner’s dissociation; and

• The other party is not deemed to have had knowledge under subdivision (e) of Section 16303 or notice under subdivision (c) of Section 16704.

Section 16303(e) deems a person who is not a partner to know of a limitation on the authority of a partner to transfer real property held in the partnership's name if a certified copy of a Statement of Denial containing the limitation is of record.   See this post regarding Statements of Denial.  Section 16704(c) provides that a person who is not a partner is deemed to have notice of the dissociation 90 days after a Statement of Dissociation is filed.
