Ang Legal separation ay proseso sa Family Code para payagan ang mag-asawa na maghiwalay ng tirahan. Gayunpaman, hindi ito nagpapawalang- bisa ng kasal. Ang grounds para dito ay:
(1) Repeated physical violence or grossly abusive conduct directed against the petitioner, a common child, or a child of the petitioner;
(2) Physical violence or moral pressure to compel the petitioner to change religious or political affiliation;
(3) Attempt of respondent to corrupt or induce the petitioner, a common child, or a child of the petitioner, to engage in prostitution, or connivance in such corruption or inducement;
(4) Final judgment sentencing the respondent to imprisonment of more than six years, even if pardoned;
(5) Drug addiction or habitual alcoholism of the respondent;
(6) Lesbianism or homosexuality of the respondent;
(7) Contracting by the respondent of a subsequent bigamous marriage, whether in the Philippines or abroad;
(8) Sexual infidelity or perversion;
(9) Attempt by the respondent against the life of the petitioner; or
(10) Abandonment of petitioner by respondent without justifiable cause for more than one year.
Para masimulan ang kaso ay kailangan magsampa ng petition sa korte para hilingin ang legal separation. Maghihintay ang korte ng at least 6 months bago magsimula ang hearing para dito. Kailangan naman ninyo magpresenta ng ebidensiya para patunayan na ang isa o higit pa sa mga grounds na nabanggit sa taas ay present para maglabas ang korte ng decree of legal separation at opisyal na madissolve na ang conjugal or community property ng mag-asawa.
