Well, what part of the field are you in? Roughneck? Driller? (Any Bakken or RR wells?)
You stand a very good chance of gaining more time. YOu will have to file a motion to modify custody order. Here are some cases that let's you know I KNOW what I'm talking about:
Arguments that Joint Custody constitutes a "fundamental right." BECK V. BECK, 86 N.J. 480, see also 23 Ariz. Law Review 785
A child has an equal right to be raised by the father, and must be awarded to the father if he is the better parent, or mother is not interested. STANLEY V. ILLINOIS, 405 US 645 (1972)
If custodial mother has boyfriend living with her, state can change custody to father. JARRETT V. JARRETT, 101 S.Ct. 329
Pro Se (Without a Lawyer, representing self) pleadings are to be considered without technicality; pro se litigants pleadings are not to be held to the same high standards of perfection as lawyers. HAINES V. KERNER, 92 S.Ct. 594; JENKINS V. MCKEITHEN, 395 US 411, 421 (1969); PICKING V. PENNA. RWY. CO. 151 F.2d 240; PUCKETT V. COX, 456 F.2d 233
You're not asking for much, and there is not ONE reason for the court to deny you that extra 36? hours with YOUR child.
File a motion, brief and affidavit, and you should be home free.
