1) Having a mental illness.
2) That the mother is not an adult
3) That the mother is not honest.
4) If the mother is unable to raise, maintain and care for the child.
5) If the mother is in serious infectious disease.
6) That the mother had previously been convicted of one of the crimes committed against honor.
7) If the mother is married
8) If the mother's religion is different from the son's religion
If the mother is a foreigner, she can take the child to live in her country, and if the father objects to that, a court ruling must be obtained. In all cases, the mother may travel with the child for a reasonable reason to any destination, if the travel does not cause harm to the child, if the guardian prevents her from traveling, it is permissible The judge may enable her to travel if it appears to him that the person who has the right to permission has abused this right.
If the custodian is a foreigner and her travel is accidental, other than residency, to her home country, the judge may request a guarantor to bring the child to guarantee her return with the child in custody.
The father or grandfather, even if he is higher, may travel with the male child who is seven years old for a reasonable period.
It is not permissible for anyone other than the father or grandfather from among the guardians and the kin to travel with the child during the custody period except with the permission of the incubator, and the judge may authorize the travel if he sees a justification for that.
If the guardian of the child in custody fears that the foreign custodian with the child will not return from her travels, stating reasonable reasons for this, the court may prevent her from traveling with the child, whenever the validity of those reasons is likely to her.
The decision to allow the child to travel shall not be in effect, except after the passing of a period of three days from the date of its issuance without appeal, or after his appeal and endorsement by the Court of Appeal.
