Middle Name Question

When naming your child with two middle names (husbands wish) lol.... do you have to hyphenate the two names together when filling out forms or birth certificate? We plan on naming him Owen Troy Phillip & then our last name. Believe me I know it's a long name and I've argued with me husband back & forth about him just having one middle name, but he insisted on his middle names being after his grandfathers who pretty much raised him. And we already have a Troy on my side and I am not to fond of Phillip.... Ugh does that sound horrible?
