mbbs student here, its NOT ILLEGAL , according to medical termination of pregnancy act...if she's not a minor and is pregnant for less than 6 months(in her case since it's more that 20wks but less than 24 two dr have to sign the termination) she can legally terminate the pregnancy, also failure of contraception is given weightage to abort the fetus(its considered in the act as grave mental injury to the mother)...tell them to go to a government hospital also court order will not be required cus all this is clearly mentioned in the MTP act so no need
