respected sir
If you're intending to keep the marriage a secret then you can get married under the Arya Samaj rituals. It is valid under the Arya Samaj Validation Act 1937. You only need someone as a witness.
Also validity of any marriage depends upon the customary rituals performed during it. Saptapadi, where bride and groom take seven steps around the holy fire is a sufficient proof including the photographs of the marriage. However, mere manglasutra and vermillion are not enough for a valid marriage. It should be performed in the form of Shastric Hindu Law and proven as a custom.
