In surrogacy arrangements, staged financial milestones are designed to protect both the intended parents and the surrogate. The primary early ultrasound milestone is the viability scan around 6 to 7 weeks, which confirms an intrauterine pregnancy and records the first visible fetal cardiac flicker. Following this, the 11-to-13-week Nuchal Translucency (NT) scan verifies steady growth, early anatomy, and a healthy heart rate, concluding the high-risk first trimester.
The next critical checkpoint is the Level-II anomaly scan at 18 to 20 weeks to evaluate fetal organ development and placental location. Later payments typically correspond to third-trimester growth and Doppler scans. Because individual agreements and clinical needs differ, please consult your fertility consultant and legal team to structure these milestones safely and transparently.

Navigating a surrogacy journey can bring both hope and anxiety, making clear clinical milestones vital. Medically, the earliest scan milestone is the 6-to-7-week transvaginal sonography, which must confirm an intrauterine gestational sac, a fetal pole, and documented cardiac activity. Without clear cardiac pulsation, payments should usually be deferred.
The second essential milestone is the 12-week NT/NB scan, confirming first-trimester stability and genetic risk markers. The third major assessment is the mid-trimester target scan (TIFFA) around 19 to 20 weeks, which thoroughly evaluates structural heart formation and general fetal anatomy. Subsequent milestones reflect third-trimester fetal wellbeing and Doppler blood flow. I encourage you to discuss tailored payment-release schedules directly with your treating fertility specialist to ensure alignment with clinical realities.

Linking surrogacy disbursements to objective medical reports provides essential reassurance for families. The first scan checkpoint is the early viability sonogram at roughly 6 to 8 weeks, which confirms that the embryo has implanted inside the uterine cavity and exhibits active cardiac motion.
The second milestone is the 11 to 13.6-week NT scan combined with fetal heart rate evaluation, confirming that the pregnancy has progressed safely past the critical early period. The mid-pregnancy milestone relies on the detailed Level-II anomaly scan at 18 to 20 weeks, verifying structural heart chambers and fetal growth. Third-trimester releases follow routine growth scans. We always recommend reviewing your scan schedules with your fertility expert to align clinical progress with administrative agreements.

When planning disbursements during a surrogacy journey, relying on verified clinical markers protects everyone involved. The fundamental early scan occurs between 6 and 7 weeks to establish fetal viability via a definitive heartbeat. A positive blood test alone is rarely sufficient for major milestone releases.
Around weeks 11 to 13, the first-trimester screening (NT scan) checks for continuous cardiac activity and normal early development. Between 18 and 20 weeks, the detailed anomaly scan (TIFFA) is indispensable to evaluate the baby's organ systems, including detailed four-chamber heart views, before clearing mid-pregnancy commitments. Later stages depend on regular growth and Doppler scans. Since every medical protocol is unique, always consult your fertility physician to determine appropriate milestones for your specific plan.

In reproductive medicine, tying staged payments to ultrasound confirmation ensures that decisions are rooted in genuine clinical progress. The initial milestone must be the 6-to-7-week dating scan, confirming an intrauterine sac, viable embryo, and positive fetal cardiac activity. The next crucial marker is the 12-week NT scan, which reassures us of chromosomal screening markers and persistent, rhythmic heartbeats.
Following this, the 18-to-20-week target scan (TIFFA) assesses fetal cardiac anatomy, organ formation, and cervical length before proceeding with mid-stage financial releases. In the third trimester, interval growth and umbilical artery Doppler scans guide final antenatal stages. Every pregnancy carries unique dynamics, so please consult your reproductive specialist to review reports personally before authorizing any disbursements.
