Answer
Based on official Jordanian legal texts
Establishing lineage in Jordanian law rests on defined routes recognized in jurisprudence and the Personal Status Law No. 15 of 2019, each with limits assessed by the Sharia court.
First: the marital bed (firash)
The default rule is that a child born to a woman in a valid marriage is attributed to her husband without any lawsuit, provided the birth was possible within that marriage according to the legally recognized minimum and maximum pregnancy durations. This is the strongest and most stable route of proof.
Second: acknowledgment (iqrar)
If a man acknowledges a child of unknown lineage as his own, lineage is established by that acknowledgment within limits — chiefly that the age difference makes the parentage plausible, that obvious facts do not contradict it, and that a child old enough to be legally heard confirms it. A valid acknowledgment cannot be retracted.
Third: evidence (bayyina)
Where paternity is denied or there is neither firash nor iqrar, lineage is proven by evidence before the court: witness testimony about the marriage, the birth, or the man's treating the child as his own; documents and correspondence; and the surrounding indications. Where needed, the court draws on medical expertise and DNA testing as scientific corroboration within its overall assessment.
General limits
- Lineage is the child's right, and courts lean towards confirming it where a legally recognized basis exists.
- Lineage cannot be established against decisive facts or where it is rationally or legally impossible.
- The sufficiency of the evidence is for the court to weigh in each case.
Because these rules are precise and fact-sensitive, present the full facts to a specialized lawyer before filing.
