Because it could be that his parents (his father) are out of town.
Regarding the transfer of fees to other places for aqiqah, there is indeed a disagreement between the scholars, which is the more significant between the two. However, this method is still legal.
Ibn Hajar Al-Haitami rahimahullah said that aqiqah can be equated with zakat fitrah, it may be issued outside the region. However, the best option is that the aqiqah is slaughtered at the place where the parents are, because it is the parents who are required to do aqiqah. This is stated in Al-Fatawa Al-Kubra, 4: 257.
Shaykh Ibn Jibrin rahimahullah stated that the more afdhal aqiqah slaughtered in the country of the child is located.
Shaykh Ibn Jibrin rahimahullah was also asked whether the aqiqah was slaughtered in the country the child was in or in the country the child was born in. It was the answer from Shaykh rahimahullah, which was even more afdhal, aqiqah was held in the country where the child was. If the parents are in different places, the cost of aqiqah will be transferred later, then the slaughter can be represented by someone else. Then the parents from different places pray for aqiqah because the blessing prayer is needed by the child.
Shaykh Al-Albani rahimahullah was asked whether it was required that aqiqah be held at the place where the child was born. The answer is, no.
The discussion above is taken from the discussion of Shaykh Muhammad Shalih Al-Munajjid at Fatawa Al-Islam Sual wa Answers, no. 132524.
