DEsERTIoN-E. NJ, Oakland Cal. The law of
California says that willful desertion is the
voluntary separation OF one of the married
parties from the other with intent to desert:
that persistent refusal to have reasonable
matrim onial intercourse as husband and wife,
when health or physical conditions do not
make such refusal reasonably necessary or the
refusal OF either party to dwell in the same
house with the other, when there is no iust
cause for such refusal, is desertion. There is
no Limitation for commencing an action for
divorce except when the cause alleged is
adultery and the action is not commenced
within two years after the commission OF the
act or after the discovery by the injured party;
when the cause of action is for felony and
the action is not commenced before the expir.
alton of two years after pardon, or the terrnfn.
alton of the period OF sentence; in all other
cases where there is an unreasonable lapse Of
me before the commencement of the action.
Unreasonable lapse of time is such delay in
commencing an action as establishes the pre-.
sumption that there has been connivance,
colusion, or condonation of the offense, or q
full acquiescence of the same with intent to
continue the marriage relations notwlthstand-
ing the commission of the ofense. divorce
must not be granted unless the plaintiff has
been a resident of the State for the period of
six months next preceding the commencement
of the action. The law does not require that
the plaintiff shall have resided six months in
one county of the State before commencing
the action.
