Buyer's Checklist

What to look for in a legal & law firms mobile app developer in Seoul

These are the questions and checks that separate legal & law firms specialists from general app agencies who will list your sector on their homepage after you sign.

SRA Transparency Rules compliance: price indication for all six mandated service areas displayed clearly-not hidden in a PDF or buried in footer text

Solicitor/barrister profile pages with SRA registration numbers, call to the bar dates, and specialisation areas-supports E-E-A-T signals and client trust

Inquiry form design with clear matter type classification: routing different inquiry types to the correct fee earner is a conversion and compliance issue

Legal Ombudsman and SRA badges displayed correctly-check placement and link accuracy; incorrect or outdated badge display is a common SRA audit finding

Content E-E-A-T: legal article authors must be named qualified fee earners with listed specialisms-ghost-written 'thought leadership' with no named author scores poorly with Google's legal YMYL classifier

Platforms & Tech Stack

Which platform for legal & law firms in Seoul?

Custom WordPress

The most common stack for Seoul law firms. Attorney/solicitor profile custom post types, practice area taxonomy, and case study pages managed by practice managers without developer involvement. Must be custom-themed for SRA compliance display.

Next.js + Contentful

Preferred for multi-practice firms, chambers, and international law firm offices in Seoul requiring performance-optimised practice area pages, multi-author article publishing, and CRM integration.

Clio Grow / Lawmatics embed

Legal CRM intake forms. These embed into any app and route inquiry data directly into the firm's matter management system. Should be used by any Seoul firm with more than 4 fee earners.

LexBlog (barrister chambers)

A specialist legal blogging platform used by UK barrister chambers. Provides SRA-aware template structures and a content community. Consider for chambers with high blog publishing volume.

Questions & Answers

Legal & Law Firms mobile app development in Seoul - common questions

Pre-brief questions that legal & law firms businesses in Seoul ask before commissioning an app project.

What are the SRA Transparency Rules requirements for a Seoul law firm app?+

SRA-regulated firms in South Korea must publish indicative prices for six service areas: residential conveyancing, probate, contested probate, motoring offences, employment tribunal claims (unfair/wrongful dismissal), and immigration (settlement applications)-where those services are offered. They must also display the complaint process, a link to the Legal Ombudsman, and the SRA Digital Badge. These are minimum requirements; the SRA web page guidance provides the full specification.

How much does a law firm app cost in Seoul?+

A sole practitioner or small firm app with SRA compliance display costs £2,500–£7,000 in Seoul. A multi-practice firm with full practice area SEO, fee earner directory, and blog is £7,000–£22,000. Barrister chambers apps are £8,000–£25,000. A Seoul office of an international firm with multi-jurisdiction pages and CRM integration is £20,000–£75,000.

Should a Seoul law firm invest in SEO alongside the new app?+

Legal keyword categories-'solicitors near me', conveyancing, personal injury, employment-are among the most competitive in Google's paid and organic results. A new law firm app in Seoul without an SEO strategy will rank on page 4 or lower within 6 months. Law firm SEO requires long-form practice area pages of 1,500+ words targeting specific query types, structured data for legal services, and local citation building in Seoul.

What should a Seoul business look for in a contract before hiring a web developer?+

A properly scoped mobile app development contract for a Seoul business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover — this is a red flag in the Seoul mobile app development market.

How long does a Seoul web project typically take from brief to launch?+

A standard business app for a Seoul company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Seoul web projects is late content delivery from the client — agree a content deadline before the project starts and the timeline holds reliably.

Should a Seoul business hire a local web developer or work with a remote agency?+

For most Seoul businesses, a remote mobile app development agency delivers equivalent or better results than a local studio — at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for mobile app development quality since 2018. Tkist serves clients across South Korea and 40+ countries entirely remotely.

How can a Seoul business verify a web developer's experience before signing?+

The three most reliable verification methods for Seoul businesses evaluating mobile app developers are: 1) Live portfolio links — the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references — ask for contact details for two recent clients in a similar sector; 3) Technical audit — ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tkist provides live portfolio URLs, verified client references, and a free technical scoping call for every Seoul project enquiry.
