Actually, in Philippine law, annulment refers to the voiding of a voidable marriage. There is also what is technically called a "judicial declaration of nullity of marriage" (JDNM) for a void marriage from the start. But these two are referred to as "annulment" by laymen.
The annulment in civil courts are completely independent from the annulment in the Roman Catholic Church, although in cases of annulment under Article 36 of the Family Code, which is taken from one of the canons of the Roman Catholic Church, the decisions of the Roman Catholic Church as to interpretation are to be given great weight by the courts. Thus, just because one's marriage is annulled in the civil courts does not mean that one can get married in the Church, and vice-versa.
I discussed the differences among annulment, JDNM, legal separation and divorce from the perspective of Philippine law here: http://diborsyo.com/50-annulment-v-l...v-divorce.html
