To transfer directly from her UR account to your UA account you would have to be members of the same household -and- you would have to be an Authorized User on her Chase card account.
Points can only be transferred to yourself, or one additional household member who is listed as an authorized user on your card account. Once you transfer points to an authorized user, that person will be the only authorized user on your account eligible to receive point transfers.
To combine points from her UR account with your UR account you would have to be members of the same household:
You can move your points, but only to another Chase card with Ultimate Rewards belonging to you, or one member of your household. If we suspect that you've engaged in fraudulent activity related to your credit card account or Ultimate Rewards, or that you've misused Ultimate Rewards in any way (for example by buying or selling points, moving or transferring points with or to an ineligible third party or account, or repeatedly opening or otherwise maintaining credit card accounts for the sole purpose of generating rewards) we may temporarily prohibit you from earning points or using points you've already earned. If we believe you've engaged in any of these acts, we'll close your credit card account and you'll lose all your points.
